The object of this invention is to provide a new and improved self adjusting weather strip for doors. This and other objectsof the invention will be illustrated in the drawings, described in the specification and point Figure 4 is a vertical section on the line 4", 4* of Figure 2.

Figure 5 is a vertical section on the line 5", 5 of Figure 2.

Figure 6 is a detail perspective view of the bolt and nut that is used for clamping the two sections of the moving bar together. Fig. 7 is a detail view of one of the StfLlZlOIlary Z bars. Fig. 8 is a detail view of ary Z bar.

Fig. 10 is a detail View of the other moving? the other station-1 These Z bars are adjustable on each other longitudi-j. nally, the bar 2 being provided with a slot 4 and the other bar 3 having a screw hole, therein through which the screw passes, This screw 5 also passes through the slot in the bar 2 so that the two bars are clamped together on the door along the upper marg n of the bars by the screw. Each bar 1s m length somewhat more than half the width of the widest door which they are intended; to lit and they can be extended or telescopedfl on each other so that the two bars together" will have the correct length to fit the width" of the door. On the lower flange the bar 3 has around opening therein andthe bar 2 has'a slot therein as indicated at 6 through which passes a boltand a nut. When the nut is loosened up this permits the onebar to slide on the other soas to'perm'it the bars 2 and '3 'tobe adjusted longitudinally oneach otherto make the correct length, after which f the nut is tightened up to "clamp the bars together and thereafter the barsare fastened to the dooi b y means of the screws 5 several of which are used but only one of which passes through the slot din the bar 2.

V, .Ea ch of the bars 2 andB is provided with the stationary studs 7 and 8..Mounted to [travel on these studs'arethe bars 9 and 10. These bar's overlap each other and onej of the bars, 9 has two horizontal slots therein 11 and "12 which are placed end to end and in line with each other- The other bar is propass length desired, thefb ars 9and together having the same length asthe Z bars 2 and 3 have when clamped together. The bars 9 and .10 are each provided'with diagonal slots. 15

and l6 whichengage'withthe studs 7 and 8 andby which the barsare raised and lowered from the full line position to the dotted line position in Figures '3 and 4, when the bars 9 and 10 are moved endwise. Between the stationary bars 2 and 3 and the moving bars Sand 10 springs'17 and Bare interposed so as to hold the bars 9 and 10 normally in the raised position as shown infull lines in all the figures, and at the right hand end'position as shojwn in Figure 2. The door is hinged on the side shown atlthe right in Figure 2 and when thedooris partially closed the bar 10 makes contact with the door casing. The bars 9 and 10 are both channel shapedfbeing bent up fromthin sheet metal. The channels open down and are filled with flexible weather strips that extend downward from the channels. The right hand fend of the bar 10 is provided with an anti-friction roller mounted to rotate in the channel which roller makes contact with the door casing. As the door closes the bars 9 and 10 move to the left as shown in Figure 2 and travel down toward the sill because of the reaction of the studs 7 and 8 on the cam slots 15 and 16. Thislpus' hes thebars 9 and I Idown'so that V the flexible'strips carriedthereby make close contact with the floor or with the" sill. The

flex e st ipsdy t ld in los c nt t with t floor and trail as the door c1oses,wthus mak ing a close fit with the floor or sill under the door. i

It will be understood that when this device is placed on the bottom are door the 'bolts 18 and 14 are loosened up. This leaves the two sections of'the inner bar and the two sections of the outer section adjustable lengthwise.

The two sections of the stationary 'bar are 7 thenadjusted lengthwiseand fastened to the door. the two sections of the stationary bar are adjusted lengthwisetheitwo sections of the movingb'ar adjust themselves length- 'wise as Well; "The bolts 13 -and"'1'4 are then tightened up to clamp the two sections of the 7 moving bar together and'the device is ready for use.
